Pollen viability, vigor, and competitive ability in Erythronium grandiflorum (Liliaceae)
Thomson JD, Rigney LP, Karoly KM, Thomson BA. 1994. Pollen viability, vigor, and competitive ability in Erythronium grandiflorum (Liliaceae). American Journal of Botany. 81(10):1257-1266
From the Abstract: "To determine how the capability of pollen is affected by lengthy exposure to field conditions, we obtained pollen samples (from Erythronium grandiflorum) that were fresh (from newly dehisced anthers) or aged, from 6-24 hr. Without pretreating the collected grains, we compared their abilities 1) to retain viability, as indicated by the Heslop-Harrison fluorochromatic reaction (FCR) test; 2) to retain germinability, as indicated by pollen-tube growth in vitro on Brewbaker-Kwack medium; 3) to sire seeds when used as a pollen donor on recipient flowers in the field; and 4) to sire seeds competitively when mixed with another donor pollen in competitive polliinations."
